ANTI-TRIMETHYL-HISTONE H4 (LYS20) ANTIBODY TRIAL SIZE RABBIT MONOCLONAL

General description

Histones are nuclear proteins that form octameric structures which bind DNA to form units of chromatin called nucleosomes. The family of histones—H2A, H2B, H3, and H4—are key players in gene regulation. They undergo a number of post-translational modifications (PTM) in response to various stimuli, including phosphorylation on serine and threonine residues and methylation on lysine residues. PTMs produce configural changes in histone proteins that may induce nucleosome remodeling and expose or hide DNA sequences from transcriptional complexes. Histone H4 lysine 20 (H4K20) may undergo mono-, di-, or trimethylation, which is catalyzed by the methyltransferase PR-Set7 (Set8 or KMT5a). Methylated H4K20 plays a role in regulating DNA damage responses, mitosis, DNA replication, and gene expression. Trimethylation of H4K20 contributes to gene silencing, and is a mark of the repressive heterochromatin state.

Specificity

Recognizes Histone H4 when trimethylated on Lys20.

Immunogen

Peptide corresponding to human Histone H4 containing the sequence [HRmethKVL] on which lysine 20 is trimethylated.

Application

Chromatin Immunoprecipitation:
Sonicated chromatin prepared from HeLa cells (1 X 106 cell equivalents per IP) were subjected to chromatin immunoprecipitation using 10 µL of either a negative control supernatant, or Anti-Trimethyl-Histone H4 (Lys20) antibody and the Magna ChIP A Kit (Cat. # 17-610). Successful immunoprecipitation of trimethyl-histone H4 (Lys20)-associated DNA fragments was verified by qPCR using ChIP Primers B-Globin. Please refer to the EZ-Magna ChIP A (Cat. # 17-408) or EZ-ChIP (Cat. # 17-371) protocol for experimental details.

Dot Blot Analysis: AbSurance Histone H3 Antibody Specificity Array (Cat. No. 16-667) and Absurance Histone H2A, H2B, H4 Antibody Specificity Array (Cat. No. 16-665), which contain histone peptides with various modifications were probed with Cat. No 04-079-S, Anti-trimethyl Histone H4 (Lys20) (1:500 dilution). Proteins were visualized using a Donkey anti-rabbit IgG conjugated to HRP and a chemiluminescence detection system.
